I saw this "Saudi Arabia has bombed ISIS in Syria"
Not in any sense that could be called serious. Meanwhile they have bombed the shit of the Shiites in Yemen, and yet failed to do anything about ISIS affiliated organisations.
I think one month with their huge air force they flew less than 6 missions in Syria. It is for show only. Areas of the Yemen look like Grozny, Syria (largely of Asad's doing) or Europe after the WWII air raids.
Qatar funded ISIS up to 2014. Often the funding was routed via Turkey. I think is some US diplomat (or maybe British) who said recently that he was told the Saudi policy was annihilation of Iran, just like Iran's policy to wipe Israel of the face of the Earth. Saudi has been furious at the US and the allies recently because its failure to do their dirty work and remove Asad. Saudis problem with ISIS is that ISIS are out of control - they do not disagree with their intentions of setting up a caliphate. They prefer the Muslim Brotherhood but the important thing for them is to remove Asad, because they could not control him.
BTW the schools which foster the beliefs which lead to extremism Saudi have spent 10s of billions setting up all over the world fostering the Pakistan Taliban (they have recently stopped funding schools there), Boko Haram and Al Shabab. This is the Royal Family's, since they are the government, doing. They have the worst human rights on the planet and yet they get treated like members of the establishment.
In the last few years finally I hear British politicians and experts critical of Saudi's or Saudi citizens funding and fostering of terrorism but at the very top the Queen and our PM maintain very strong relations with them when they should be pariahs.
